Lolz... we always need to keep reminding people on global websites and fora to come out of their Western-centric insularity.
This poll misses the two most important names: Xi Jinping and Narendra Modi
Xi Jinping is the most hated politician on the planet right now, simply because 90% of India (which alone is around 17% of the global population) hates him. Combine this with around 20% of China (as reported by media in the Philippines and Taiwan), as well as roughly 75% of the Philippines, Taiwan, Japan and South Korea... and a sizeable population in the West, and the total numbers make Xi the most hated politician.
Modi is a close second, as he is hated by roughly around 25% of Indians (which is almost the entire US population), all of Pakistan and Bangladesh (which together again are more than the US population) as well as all Islamic countries besides the UAE, Oman and Saudi Arabia... apart from a lot of people in the West.
In terms of numbers, Netanyahu has overwhelming support in India, which comes close to negating the hate for him from Western and Muslim countries combined, but maybe not quite fully.
Putin is an extremely popular leader right now when you look at the global perspective, and not merely the Western one. Apart from the Russian population itself, Putin has the majority support in both China and India, and this alone is enough in terms of numbers to negate the number of his haters in other parts of the world combined. Add to this the support for him in Iran and Turkey and most of the Arab world, and most of sub-Saharan Africa, and he is right now the world's most popular or positively perceived politician in terms of numbers.
Everyone needs to remind themselves that the Western bloc - Europe (excluding Russia), the US, Canada and Australia combined - has fewer people than either China or India... and given the waning importance of the Western bloc globally in terms of economic and political power, increasingly global opinion is being shaped and global action directed by the non-Western world. This will only increase in the future... so the results of polls about who is what on "planet Earth" will be inaccurate and irrelevant if they are Western- or Euro-centric.
